Be it known'that L JOHN "V. WICAD-AM', a citizen of the United States,and resident of the borough of Manhattan, in the jcity-=and State'of NewYorkfhaveinvented a new and useful Improvement in Railway G-ar L erlysquared with respect'to-each-other.

Trucks, o'f-wh-ichthe following is a-specification.

At present it isthe'usualpracticeincar construct-ion to have the 'loado'f-thecarsupp'ortedby the trucks at pointshetween or oflt-set from theside frames. 'This construction requires'the use-of veryheevyr'tru'ckholsters to-properly transmit the loa dfto the side "frames and keep theside iframes prop- My invention consists in providing nstructure inwhich the car l'oad is supported: upon the side frames independently of--a "truck bolster, the side frames of each pair being properly spacedapertoy acrossconnecting piece which receives none of the load 'of'thecar. This arrangement ermits of a materiaFreduction 1n the'weig tof thetruck and also in the cost of manufiaeturing'the sarne. My inventionconsistsf-urther in providing certain improvements in the construction,

form and arrangement o'tthe several ;.parts I of a truck of thischaracter having built us side fra mes,'rocker' hearings being interposefibetween tl e bodyof the car and the truck,

Fhe-topand bettomerch-bars-l and 2 intermediate their ends are connected by two Vvertical'columns'fi forming spring 'cap guides rigidly spaced apart andsecured to -the'itop bot-tom a rch bars by through iboit-s :7. Thesecolumnsare "provided with shoulders 18 011 which the sprin seat' f)rests.

The spring'cap :is denotedby l0 end-it is "fitted 'to slide vertioallybetween the columns 6. "Springs =11 are interposed between the springseat 9 and springcap 10. In the present instance "four coil springs 11:'are shown, the (spring seat being provided'with 'four upw-ar lyextended lugs 12 for centeroeiving and positioning the upper thesm'd-sprin s. v

These rockerhearings, in the present- 111-- opening 17 therein for receiving thensual piece being held in position by-the lugs 21, 23. The top andbottom of each of these pieces may be of spherical form as shown at 26,27, and the engagement of tliese pieces with their lugs is such that thebody bolster 19 of the car may have a limited movement n any direction,the tops and bottoms of the. pieces 24, 25, serving as a rockingbearingbetween each spring cap 10 and, the body bolster.

The truck wheels are denoted by 28 and the axles by 29. i

From the construction herein set forth it will be seen that the use of atrneli'bolster is obviated as the load of the car is supported by theside frames through the springs 11. spring caps 10 and rocker bearmgs.

It is to be understood that these rocker bearings may be made in variousshapes and sizes to suit different requirements: also that the form oftlie side frames and connecting piece maybe varied from that shown anddescribed therein. and that various changes might. be made withoutdeparting from the,

spirit andscope of my invention; hence I do not wish to limit myselfstrictly to the construction herein set forth. but
